Background: Obesity is reaching epidemic proportions globally, with a threefold increase from 1975 to 2016. The percentage of obese adolescents aged 12-19 years increased from 5% to 21% over the same period. Social Cognitive Theory can determine human behavior in limiting food intake (diet) and regular physical activity. A valid and accurate measuring instrument for the factors influencing obesity is essential. This study aimed to determine the reliability of measuring instruments for diet, physical activity, social support, and Social Cognitive Theory on overweight and obesity in adolescent girls. Subjects and Method: This study used primary data. As many as 15 study subjects were selected by simple random sampling. The value of item-rest correlation and Cronbach’s alpha were examined using split half method run on Stata 14. Results: Dietary intake questionnaire haditem-rest correlation ≥0.20 with Cronbach alpha= 0.77. Physical activity questionnaire had item-rest correlation ≥0.20 with Cronbach alpha= 0.78. Social support questionnaire had item-rest correlation ≥0.20 with Cronbach alpha= 0.88. Social cognitive theory questionnaire had item-rest correlation ≥0.20 with Cronbach alpha= 0.89. Conclusion: Dietary intake, physical activity, and social cognitive questionnaires are reliable to be used. Keywords: reliability, item-rest correlation, Cronbach alpha Correspondence: Yeti Rahelli.

Background:This study aimed to develop and evaluate the construct validity and reliability of modernized social cognitive measures relating to physical activity behaviors in adolescents.Methods:An instrument was developed based on constructs from Bandura’s Social Cognitive Theory and included the following scales: self-efficacy, situation (perceived physical environment), social support, behavioral strategies, and outcome expectations and expectancies. The questionnaire was administered in a sample of 171 adolescents (age = 13.6 ± 1.2 years, females = 61%). Confirmatory factor analysis was employed to examine model-fit for each scale using multiple indices, including chi-square index, comparative-fit index (CFI), goodness-of-fit index (GFI), and the root mean square error of approximation (RMSEA). Reliability properties were also examined (ICC and Cronbach’s alpha).Results:Each scale represented a statistically sound measure: fit indices indicated each model to be an adequate-to-exact fit to the data; internal consistency was acceptable to good (α = 0.63−0.79); rank order repeatability was strong (ICC = 0.82−0.91).Conclusions:Results support the validity and reliability of social cognitive scales relating to physical activity among adolescents. As such, the developed scales have utility for the identification of potential social cognitive correlates of youth physical activity, mediators of physical activity behavior changes and the testing of theoretical models based on Social Cognitive Theory.

Abstract Background: Eating habits and physical activity are important factors for the development and prevention of non-communicable diseases. Therefore, the objective of this study was to analyse the beliefs, behaviours, and experiences of dietary and physical activity habits based on the constructs of the Social Cognitive Theory (SCT). Methods: An exploratory study with a qualitative methodology and a phenomenological study design was conducted using focus groups, in-depth interviews, and indirect non-participatory observation. The sessions were audio-recorded and transcribed with prior written informed consent. Data analysis was performed using a hybrid approach.Results: Workers reported that they do not eat vegetables or fruits daily; however, the consumption of fast food and sugary drinks was frequent. Participants’ behaviour is influenced by environmental factors such as reinforcements (economic bonus and company meetups & events), barriers (workplace policies) and facilitators (availability of drinking water, free tortillas , dining rooms, and recreational areas); and personal factors, such as low self-control when when choosing foods from the grains group (e.g. Mexican pastries, noodles and breads), and emotional confrontation (e.g. few workers try to use strategies to confront their emotions and avoid them from affecting their eating and physical activity). On the other hand, participants indicated not feeling capable of eating specific foods due to their taste, for example vegetables, and doing physical activity due to factors such as time. Finally, other key elements influencing workers’ behaviours were observational learning (participants eating behaviour and physical activity are influenced by their coworkers and family’s behaviours), social support (coworkers and family) and outcome expectations (participants’ hoping to improve their health by eating healthy and physical activity behaviours).Conclusions: Workers’s eating behaviour and physical activity could be modified if different influencing factors are simultaneously addressed. These findings will contribute to the development of worksite health programs, based on the SCT, to address the key factors that could improve workers’ eating behaviours and physical activity. Keywords: Eating habits, physical activity, adults, workers, workplace programs, qualitative research, Social Cognitive Theory.
